Trinity Mirror has alerted the stock market to the figures, which will be discussed at the company's annual general meeting today by outgoing chairman Sir Victor Blank. Blank will hand over to the recently appointed Sir Ian Gibson.
The company left little room for optimism in its stock market statement, though it alluded to the fact that the early part of 2005 had been comparatively strong.
"The difficult advertising market conditions experienced in 2005 have continued into 2006. While comparatives will ease as the year progresses management continues to run the business on the assumption that the advertising environment will remain very challenging."
The figures show that its national newspaper division is doing worse than its regional division.
National newspaper ad revenues fell 14.1%, with the UK papers down 15.7% and the Scottish papers down 9.6%.
Regional newspaper ad revenues fell 10.4% with declines in all categories apart from property. Recruitment advertising fell 22.6% and motors fell 12.9%.
There is a silver lining if revenues from the clutch of recruitment and property websites acquired by Trinity Mirror over the past year are factored in. This would reduce the 11.8% overall like-for-like decline to 9.6%.
In addition, the company has increased circulation revenues by 2.4% for the regional division and 0.7% for the UK national titles, though the Scottish national titles were down 4.2% due to price competition.
Trinity Mirror cut hundreds of jobs across the UK at the turn of the year in an effort to cut costs. Although it claims the amount is less than the 770 reported, it has not disclosed the extent of the redundancies. It is aiming to achieve another £15m of cost savings during 2006.
